I have just checked coupons. The lowest price I could get is 6.89 USD for 3.1A 3-Port USB Charger (in Banggood). Basically copy coupon, view price history or create e-mail price alert. What is the best price?
Latest coupon and price update (UTC):
Banggood (6.89 USD)
Banggood warehouse is located in China. I have no active coupons for you right now. I think you want to know if the price is good. Looks like this is great price. I didn’t track lower than that in CouponsFromChina database ever.
